soft shift and no 4th after rebuild

I have a 700 in a Datsun 4x4 with a sbc in it. I had a pull a part trans in it at first. I did have upgraded 2-4 servos in it, but that it. with the TV cable a Little on the tight side it would chirp 33s no problem going to 2nd every time. ofter i broke the center support race and rear planets. I did a rebuild. i also installed a trans go kit, except the plug that goes into the 4th accumulate boar. Anyway after rebuild i took my drums to a tranny shop so they could air check it and install new shaft seals for me. they also rebuild my pump for me. any way no slips. it sifted to over drive once and ant done it since. the shifts are softer than when it was a junk yard tranny even if i pull the TV cable real tight. any ideas what i done wrong?
